HYDRO'CARBON-BUR'N ER.

SPECIFICATION forming part of Letters Patent No. 532,202, dated January 8, 189715.

Application filed March 8, 1894. Serial No. 502,889. (No model.)

.T all whom t mayconcern:

Be it known that I, WILLIAM R. JENKINS, of Bellefonte, county of Centre, State of Pen nsyl- Vania, have invented certain new and useful Improvements in Hydrocarbon-Burners, of

vWhichthe following is a specification, reference'being had to the accompanying drawings. The object of my invention is to produce certain specific improvements in hydro-c`ar bon burners offthat class referred to in my application ,Serial No. 490,039, filed November 4, 1893, whereby the general efficiency of the burner is improved, and convenience of manipulation obtained.

In the accompanying drawings: Figure 1 is a side elevation of my burner. Fig. 2 is a similar View at right angles thereto. Fig. 3 is a central vertical section on the line 3-3 of Fig. 2.

Referring to the figures on the drawings: l indicates the base of my burner, which is preferably dish-shaped and upon which is preferably supported a generator 3, as by means of a tube 4 screwing into the base and into the generator, with the interior of which itcommunicates and through which oil may be supplied to the generator. The generator, may be entirely hollow, or the casting may be provided with a central cylindrical wall 5,'which is, in practice, filled by a plug 6. The bottom of the generator is preferably inversely conoidal, as illustrated, the apex of the conoidal bottom being formed by the block, when a block is employed.

7 indicates a downwardly depending burner tube which preferably extends within the interior of the generator to a plane near the top thereof. The burner tube terminates in an inwardly deflected tip 8 which may be made of a separate piece, as illustrated, secured to the end of the burner tube and closed at its lower extremity, or it may be made ofa single piece with the tube. The Vtip is pierced directly underneath theapex of the bottom of the generator, by a vent `9.

`10 indicates a combustion chamber supported over the vent by air branches 11 which may be cast integrally with the base and with the walls of the combustion chamber. These air branches communicate with the interior of the combustion chamber and are flared at their outer ends, as illustrated at 12. The obflected from the generator around the walls of the air ,supply branches which thereby maintains them at a high temperature, thoroughly heating the air which is supplied to the combustion chamber. It should also be noticed that the flare of the air supply branches is provided at the bottom so` that ample airspace is provided around them for access directly to the vent of the air burner, in order to perfectlysupport the combustion in close proximity to the vent.

13 indicates a needle valve carried in a suitably packed valve case 14 and movable lengthwise to and from the vent 9 for the purpose of regulating the flow of gas into the combustion chamber. Upon its lower end the valve is provided with a transversely slotted piece 15 within the slot of which an eccentric pin 16 of a shaft 17 works. The shaft is carried in a suitable bearing frame 18, so that by its rotation it may raise or depress the valve. handle 19 on its outer extremity for convenience of manipulation. The bearing frame is preferably detachable and is' secured to a flange 2O depending from the bottom of the Sis Itis preferably provided with a wheel example an abutment screw 21.

In operation, oil is in the first place permitted to (low out of the vent 9 into the dishshaped base, until a sufficient amount has accumulated therein for the purpose of initially heating the generator. By turning the shaft 17 the flow of oil is then stopped, the oil in the base ignited and the generator heated by the products of combustion striking against the bottom thereof. As soon as the oil in the base is burned out the generator will be sufficiently heated to generate gas which, upon opening the vent 9, may be ignited Within the combustion chamber. After the initial combustion, the products of the burning gas are sufficient to keep the generator in operation and the flame may be controlled by raising or lowering the valve.

What I claim is- 1. In a hydro-carbon burner, the combination with a generator having a deiiecting bottom, a burner tube communicating with the same and provided with a vent under the generator, a base in proximity to the generator and intermediate air supply branches supported upon the base and discharging above the vent in the burner tu-be, substantially as set forth.

2. In a hydro-carbon burner, the combination with a generator having a defiecting bottom and burner tube communicating with the same and provided with avent under the generator, of a base, outwardly fiaring air supply branches carried upon the base in proximity to the deflecting bottom of the generator, and discharging above the vent of the burner tube, substantially as and for the purpose specified.

3. In a hydro-carbon burner, the combination with a generator and burner tube communicating with the same, and provid ed with avent under the generator, of a base and horizontal air supply branches borne thereon, a

3o combustion chamber located between the burner tube and the generator, said air supply branches opening into the combustion chamber, substantially as set forth.

4. In a hydro-carbon burner, the combination with a generator and burner tube communicating with the'same, and provided with a vent under the generator, of a base'l and iared horizontal air supply branches borne on the base having their upper walls in proximity to the generator and their lower Walls elevated to permit access of air to the vent and a combustion chamber communicating with the air supply branches and located between the burner tube and the generator, substantially as set forth.

5. In a hydro-carbon burner, the combination with a generator, a burner tube communicating therewith and a vent in the tube underneath the generator, of a base, a combustion chamber, air supply branches carried upon the base in proximity to the generator, a needie valve carried in operative relations with the vent and mechanism for operating said valve, substantially as set forth.
